Patent DE-2834840-A1 (DE)
Title: Synchronising cone for vehicle gearbox - has surface formed of small cavities for higher wear resistance
Inventor: MITTELBACH BERND DR
IPC: F16D23/02
Filed: 1978-08-09
Abstract: The conical friction surface of a synchronising cone contains axial oil grooves. The remainder of the conical surface has cavities (4) formed by spark-erosion. This type of surface gives friction coefficients which are as good as known synchronising cones, but has a higher wear resistance, while manufacture is more economical. The friction surface has a surface finish at 25-50 mu m.

Title: Low height concrete mixer having annular horizontal drum - in which depending, hollow agitator arms circulate to supply water (sw 11.9.78)
Inventor: FEJMERT BERNHARD VALDEMAR
IPC: B01F7/16
Filed: 1978-08-09
Abstract: Above the central region of the annular drum there is mounted a rotor coupled to a drive mechanism. The rotor comprises a hollow casing from which horizontal tubular arms extend radially, each arm mounting an agitator arm which extends downwardly into the mixing space. The internal cavity of the rotor is connected to a source of liq. which is thereby enables to flow through the radial arms and the agitator arms into the mixing space. Pref. the agitator arms are pivotally connected to the radial arms through a resilient coupling. The power may be transmitted to the rotor through a transmission unit located below the rotor body and in the central space of the annular drum. The mixer is intended for concrete. It is of low overall height, easily cleaned, and requires only a single liq. supply path not involving the use of hoses.

Title: Automatic dairy cattle electronic identification system - uses passive transponders returning identifying counter reset signals to fixed interrogation unit
Inventor: RODRIAN JAMES A
IPC: G07C9/00
Filed: 1978-11-21
Abstract: A low cost automatic electronic animal identification system, esp. for identifying dairy cattle, uses small passive transponders attached to the animals. The transponders derive power via a rectifier from the signal received from a transmitter-receiver. The system is compatible with commercially available data processing systems in that the identification numbers are produced in a counter in binary form. Pulses from a pulse generator are counted in a first counter which produces the sum at an output when a switch signal is received. The pulse generator output drives a second counter set to an identification number in the transponder via a signal transmission coil in the fixed unit and a detector coil in the transponder. The seconder counter output is similarly fed back to the fixed unit where it resets the first counter, thus causing identification number display.

Title: Foil coated core plate mfr. - by applying only linear central pressure to foils and charging them electrostatically
Inventor: BRUESSEL RICHARD ING GRAD
IPC: B29C63/00
Filed: 1978-12-04
Abstract: The one-sided or two-sided application of foils on core plates, such as chip-board or fibreboard plates, uses two large-dia. rollers which apply the foils to the core plate without any pressure. A pair of wheels, one over and the other under the sandwich plate, apply a linear pressure along the centre line. In the following station, two ionisation plates apply an electrostatic charge across the full width so that the foils are fixed thereby. The final operation is done in a press with heated platens. This ensures that even foils of large format are applied without stress to a sandwich plate.

Title: Blade adjuster for scale removing machine - uses sensor which detects phase difference of drive to operate adjusting screw
Inventor: LINDEMANN WOLFGANG DIPL PHYS D
IPC: B23B29/04
Filed: 1979-03-20
Abstract: A machine for removing scale from steel bars (9) has a blade (8) mounted in a housing (1) attached to a hollow shaft which runs in bearings (5).

Title: Water economy constantly ready lavatory flush box - has additional outflow, with closing valve, at level for reduced volume flush
Inventor: JANSEN HELMUT DR MED
IPC: E03D1/14
Filed: 1979-05-25

Title: Treatment of flowable particulate solid with liq. - using flow passage with set of conical projections to induce vortices with good mixing
Inventor: GUYER AUGUST DR ING
IPC: B01J16/00
Filed: 1979-08-02
Abstract: Particulate solids which can flow are contacted with a fluid as a suspension. The system has at least one contact space which is essentially a vertical channel where the solids are introduced into a stream of the contact fluid. The surface of the channel has a continuously changing shape. The walls have zig-zag profile and the passage itself can be of diverging cross section. The sharp edges of the points of the zig-zag locates vortices in the fluid and thus ensure good mixing. The process is for mechanical, thermal and/or chemical treatment of particulate solids esp. purification of crude salt crystals. The process ensures a narrow well defined residence time spectrum and allows the residence time to be tailored to the particle size range of the material.

Title: Redn. of nitrogen- and sulphur-oxide emissions from combustion - by preheating the fuel e.g. by combustion gases to 150-450 deg. C
Inventor: HOLZER KLAUS DIPL ING
IPC: F23D14/66
Filed: 1979-11-02
Abstract: Pollutant emissions of SO2 and/or NOX during the burning of conventional fuels are reduced by preheating the fuel to at least 150 deg C before it comes into contact with high concns of O2. The temp of preheating depends on the fuel (being lower for lighter fuels) and on the effect required. Partic. pref are temps above 200 deg C, to a max of approx 450 deg C. Where a gas-atomising nozzle is used, both the fuel and the atomising medium (eg air) should be preheated. Preheating may be done in a heat exchanger, pref against combustion gases. Process is simple, and can be added to existing installations without great expenditure. The CO concn is also reduced.

Filed: 1979-11-07
Abstract: An arrangement for determining heat consumption of thermal loads is esp. for room heating water systems and measures heat flowing in a given time from the hot water throughput and the inlet and outlet temp. It enables a relatively accurate determination of heat consumption without high technical or financial cost. The time integral of the product of hot water throughput, specific thermal capacity, and temp. difference between hot water feed and return is determined using electromechanical, electronic, or mechanical counters. A flow resistance meter (16,17) is mounted in each of the inlet (12) and return (13) pipes. The measurement value outputs of the flow resistance meters are connected to a differential indicator via measurement transducers (R1,R2) consisting of variable electrical resistances. The two flow resistance meters are of identical dimensions.
